Geophysical monitoring of initiated in-situ bioremediation of chlorinated solvent contamination
(2019) 25th European Meeting of Environmental and Engineering Geophysics, Held at Near Surface Geoscience Conference and Exhibition 2019, NSG 2019- Abstract
Contaminated ground is a severe problem which is present in many countries, and it is of great importance to find efficient solutions to deal with it. In Sweden, there is a trend in the industry to move towards alternate remediation methods and on that scope in-situ bioremediation has received a lot of attention. The main challenge with in-situ bioremediation is to verify that the treatment has the intended effect, and it is hence important to understand the changes that happen in the subsurface and monitor them over time. The scope of our work is to use geophysics to extrapolate the punctual information from groundwater and soil samples and acquire a better understanding of the changes in the subsurface during in-situ bioremediation of...

Contaminated ground is a severe problem which is present in many countries, and it is of great importance to find efficient solutions to deal with it. In Sweden, there is a trend in the industry to move towards alternate remediation methods and on that scope in-situ bioremediation has received a lot of attention. The main challenge with in-situ bioremediation is to verify that the treatment has the intended effect, and it is hence important to understand the changes that happen in the subsurface and monitor them over time. The scope of our work is to use geophysics to extrapolate the punctual information from groundwater and soil samples and acquire a better understanding of the changes in the subsurface during in-situ bioremediation of the contaminated soil. In this work we have made a permanent installation in one of our field sites, in Alingsås, where a pilot bioremediation test is taking place to treat the contaminated soil. The autonomous system can measure the resistivity and chargeability distribution in the subsurface. The results indicate promising correlations with the geophysical signature and the contaminant. Currently we are investigating the correlations between the groundwater samples and the time-lapse imaging acquired while working towards real-time monitoring.
